But a couple of days ago i did drive into town & buy some red wine. |

One strike & it is out. --- End quote --- No that's not how it works (unless you feel the need to destroy it). Popper falsifiability is stretched too far as a dogma of science these days. Evidence is probabilistic at best, a battle between confirmation bias and entrenched consensus at worst. People don't believe evidence, they believe what they like. The legal profession has it more technically right, with this playing off of "alternative facts" against each other until one person makes a judgment based on considerations of reasonableness, it stops when one party runs out of money or the system gets sick of it and locks in an answer and moves on. Or is that science? (What would I know - I didn't know Karl Popper was my 'alma mater' until a few days ago, to the horror of those around me. The fact there is a "Popper" building should have perhaps triggered some thoughts, maybe I look up at the pigeons and think a mental "bdrrrtu" (or whatever they say) or perhaps even say one, and ride on oblivious to all else beyond their lofty lofts.) It could turn out one of your ideas works better than anything currently around, say your idea of electons fits with a theory similar to holes in a semiconductor and the "balls in pipe" analogy, such that an entangled pair of photon and electron behave like a composite particle and nobody can deny. It might be named after you by some subsequent great, but nobody will remember your surface electrons theory for example. The thing is, you don't decide. Karl Popper doesn't decide. It's down to what people think. An objective reality clearly exists at the individual level, but society as a whole is limited to belief. --- Quote from: aetherist on February 11, 2022, 10:24:13 pm ---Old electricity has not even faced a ball, it has been allowed to walk around & around the bases while everyone cheers & goes bananas every time it steps on the home plate, i think that old electricity duznt even own a bat. --- End quote --- That's because it is 100-200 years old. It faced those balls in its youth, the cheering never stopped. |

--- Quote from: aetherist on February 11, 2022, 10:02:09 pm ---An electon propagates along the surface of a wire at the speed of light (in vacuum)(or in air)(or in plastic). --- End quote --- What is an "electon"? I assume you are referring to an electron. An electron cannot move at the speed of light since its mass becomes infinite as it approaches the speed of light. I suggest that you read the book entitled "The Physics of Vibrations and Waves" by H.J. Pain. Here is an excerpt: "At the outset we must be very clear about one point. The individual oscillators which make up the medium do not progress through the medium with the waves. Their motion is simple harmonic, limited to oscillations, transverse or longitudinal, about their equilibrium positions. It is their phase relationships we observe as waves, not their progressive motion through the medium. There are three velocities in wave motion which are quite distinct although they are connected mathematically. They are 1. The particle velocity, which is the simple harmonic velocity of the oscillator about its equilibrium position. 2. The wave or phase velocity, the velocity with which planes of equal phase, crests or troughs, progress through the medium. 3. The group velocity. A number of waves of different frequencies, wavelengths and velocities may be superposed to form a group. " In general, the wave velocity is not equal to the particle velocity. |

No wave of any kind can propagate at a velocity of any kind unless the medium moves at least briefly at that velocity or more. Either Pain is wrong or u is wrong. |
